Description
Ride faster and smarter than you previously deemed possible with the Stages Cycling Ultegra R8000 G3 R Power Meter. With chainrings included, the G3 R is quick and easy to fit and can be paired with a left-hand Stages crank arm for dual-sided power measurement. With a battery lifespan of 200+ hours, you can enjoy mile after mile of uninterrupted riding, while Stages have added an LED indicator, warning you when the battery levels drop. Replacement is also made quick and simple thanks to a single Phillips-head screw.
Boasting an IPX7 water resistance rating and featuring Stages' tried and tested active temperature compensation, the G3 R provides reliable data in varied conditions, ideal for those looking to train all year round.
Featuring a cadence range between 20 and 220 rpm and accurately measuring up to 2500 Watts of power, the G3 R has the credentials to appease anyone from beginners through to professional cyclists.
Please note, this product is supplied with only the drive-side crank arm.
To help find your current crank model, check the inside of the crank arm for the model and length. The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm Allen key wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
Still unsure? See this illustration for a guide of where to measure.
